Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

This turbine or air driven motor produces a steady output torque when run either slow or fast and produces very little axial thrust on the shaft bearings. The turbine consists of an outer housing 10 having a nipple 12 through which the air under pressure is admitted. The air poises between the housing 10 and a stationary sleeve 14 which has nozzle openings 16 therein to allow the air to pass through and impinge against pockets 18 machined on the circumference of the turbine. These angularly disposed pockets 18 are aligned with the angularly spaced holes 16 in the sleeve 14 for direct driving purposes via the air. The pockets 18 carry the air until it can be exhausted through suitable openings in the sleeve 14 and in the housing 10.

Air Driven Motor

This turbine or air driven motor produces a steady output torque when run
either slow or fast and produces very little axial thrust on the shaft bearings. The
turbine consists of an outer housing 10 having a nipple 12 through which the air
under pressure is admitted. The air poises between the housing 10 and a
stationary sleeve 14 which has nozzle openings 16 therein to allow the air to
pass through and impinge against pockets 18 machined on the circumference of
the turbine. These angularly disposed pockets 18 are aligned with the angularly
spaced holes 16 in the sleeve 14 for direct driving purposes via the air. The
pockets 18 carry the air until it can be exhausted through suitable openings in the
sleeve 14 and in the housing 10. More than one row of nozzle openings 16 can
be provided, thus producing a higher torque if desired. In this design, the driving
force is applied to the peripheral surface of the turbine and not axially along the
shaft. Thus, no axial force is applied to the bearings to cause wear.
